ABSTRACT:
A roller bearing is composed of a truck rail, a casing mounted astride the truck rail and a number of rollers arranged in a parallel-roller type; a return passage formed in the casing is connected to a truck face of the truck rail through a direction change passage for an infinite rectilinear motion, further in a part of the direction change passage there is formed a twisting passage, which makes it possible to form the truck groove and the return passage approximately on the same horizontal plane. Further in a bearing having four rows of endless circulation passages, the twisting passage can be formed either only in a pair of corresponding roller-rows or in the all of the roller-rows. Thus there can be provided a roller-bearing having the lowest possible sectional height, and comparatively a great load capacity, at a reasonable price. 7
